(C) and cold air only is directed to the windscreen.
(Fig. 2).
Further movement towards the "DEFROST"
position gradually closes valve (C) and opens valve
(D) allowing warmed air to enter the Demist
Chamber (Fig. 3) until at the "DEFROST" position
valve (C) Is fully closed and valve (D) is fully open
(Fig. 4). The demist air temperature Is now the
same as that entering the car.
Movement of the "Screen" lever to the "DE-ICE"
position restricts the "Car" air outlet and so
Increases the "SCREEN" air flow to maximum (See
Fig. 5).
N.B.-The water control valve Is not Interconnect­
ed between the "Car" and "Screen" controls.
Therefore, It Is necessary to set the "Car" control
lever between the "Cold" and "Hot" positions to
obtain heated air at the windscreen.
ADJUSTMENTS
All the interconnected mechanism is outside the
heater, therefore, all the adjustments are made
externally.
In the event of malfunction It is Imperative that a
check be made to ensure that the cable run, fitting
and adjustment of the control cables Is normal, and
that full movement Is achieved without slack.
:;N�!L
Adjust the cables at the heater unit end.
CABLE
If normal function is not· restored or derangement
of the linkages has inadvertently occurred, proceed
as follows:-

clockwise and re-tighten screw "K".
(b) The water valve lever is Interconnected
with the air mixing valve and the air outlet
valve. When the water valve lever is fully
anti-clockwise the air mixing valve should
be at rest In the horizontal position; to
check this slacken screw (L) (this will allow
the valve to drop should it be out of
position) an� now retlghten screw (L).
(c) If the air outlet valve Is not fully closed,
move the "Car" lever away from the "off"
position until the water valve lever (H) ·
